Thought I'd start a thread to discuss this. The addition of flat value increases to infusions.

Maybe something like 2500 for legendary, 500 for rare, 150 for uncommon, 30 for common? If you want to know why I chose those numbers:

The nearest vanilla baseline for comparison would be bionics: Like infusions, they enhance a pawn's stats. A vanilla bionic limb is about 1000 silver for a 25% increase in one body part. But since legendary infusions give that same increase across the entire body and not just one limb, it should be higher.

However, there's more than just the stat increase itself to consider. Due to the fact infusion slots are limited on equipment, stronger infusions have more utility than just their stats would indicate (e.g., a single +10% stat infusion is considerably more useful than two +5% stat infusions, since the former frees up an extra infusion slot). So the value should increase exponentially the rare an infusion is.

I'd also recommend tweaking price based on usefulness. Ones like wilderness should be half the value of others that tier.

Finally one last thing to note: Weapon infusions are much more useful than armor infusions (a single weapon and infusion can be life-or-death, while one can very rarely say the same about armor infusions, except maybe those that increase armor). However, weapon drops don't become tainted like armor, so you can recover many times more (sellable) infused weapons than infused armors. So while more valuable they may also need a price nerf. Ideally, the best solution would be to make weapon infusions much rarer than armor ones due to how much easier infused weapons are to capture, but not sure if the mod allow you to differentiate between weapons and armor infusion appearance rate.
